Primary use | Uses the sun’s energy to heat fluid, such as water in space heaters, water heaters or swimming pools[5] | Uses the sun’s energy to generating electricity |
Efficiency in cloudy weather | More efficient than solar PV panels, even in overcast or windy weather. Efficiency can be as high as 90 per cent[6] | Around 15-20 per cent for monocrystalline and 13-16 per cent for polycrystalline |
Installation cost | £2,500 – £5,400[7] | Around £5,200 – £8,000 |
Maintenance | Higher maintenance due to more parts and the circulation of fluid[8] | Low maintenance – occasional cleaning of panels required |
Energy storage | Tank needed to store the water that gets heated[9] | Battery storage allows for SEG payments |
Best for | Homes with high hot water needs | Powering homes with solar energy |
Lifespan | Up to 20 years[10] | Upwards of 30 years |
